How Playlist Length Calculator handles playlist requests, analytics, and support messages
2026/08/30
Who We Are
Playlist Length Calculator provides a free tool for estimating the watch time of public YouTube playlists. The calculator does not require you to create an account or connect a YouTube account.
Questions about this policy can be sent to support@playlistlengthcalculator.site.
Information We Process
When you use the calculator, we process the public playlist URL you submit. We extract the playlist identifier, request publicly available playlist and video duration data, and return the calculation to your browser. A successful public result, including public playlist and video titles, may be cached for up to 15 minutes so the service can respond efficiently. The cache key is a hash; it does not contain the raw playlist URL or identifier.
Our hosting and security providers may process standard technical request data such as IP address, browser and device information, requested URL, and security or error events. We use the IP address temporarily to apply an abuse-rate limit to calculator requests.
Analytics
We use Google Analytics and Microsoft Clarity to understand aggregated site usage and improve the calculator. These services may process online identifiers, device and browser information, pages viewed, and interaction data through cookies or similar technologies.
Google Analytics loads when you visit the site. Microsoft Clarity remains optional and loads only when the browser already has a saved analytics preference allowing it. The calculator remains available when browser settings or extensions block analytics.
How We Use Information
We use the information described above to:
- calculate the duration of a public playlist you request;
- operate, secure, cache, and rate-limit the service;
- diagnose errors and prevent abuse; and
- measure and improve the site.
Service Providers and Sharing
We use the following providers to operate the service:
- YouTube Data API to retrieve public playlist and video metadata needed for a calculation;
- Cloudflare for hosting, caching, security, rate limiting, and operational logging;
- Google Analytics for site analytics; and
- Microsoft Clarity for optional analytics when an existing browser preference allows it.
We do not sell personal information. We do not currently display third-party advertising or run Google AdSense on this site. If that changes, we will update this policy and the relevant consent controls before enabling advertising.
Retention
Successful public calculation results are cached for up to 15 minutes. Technical logs and analytics data are retained according to the applicable provider configuration and policies, unless a longer period is required for security, fraud prevention, or legal obligations.
Your Choices
You can control or delete analytics cookies through your browser settings or extensions. Blocking analytics does not prevent the calculator from working, though it may not remove information that a provider has already processed.
Changes to This Policy
We may update this policy when the service or its data practices change. The effective date at the top of this page shows when it was last updated.
